SIGNAL BELL...

SPECIFICATION forming part of Letters latent No. 656,768, dated August28, 1900. Application filed February 8, 1900. Serial No. 4,551. (Nomodel.)

This invention relates to improvements in V signal-bells, and moreparticularly to that class which is designed for use on street-railway,tramway, and like vehicles; and the object of the improvements is toprovide means whereby such signal-bells or signal devices are made morereliable and more efiective in use; and with this end in view theinvention consists of a signal device comprising two independent'bellsand a suitable clapper-andplungermechanism adapted to sound the saidbells simultaneously, so that if one becomes damaged or broken the otherstill remains effective.

In the accompanying drawings, Figure 1 is a side elevation, partlyinsection, of the improved signal-bell, the clapper-and-plunger mechanismbeing in the position of rest; and Fig. 2 is a similar view showing theparts in their working position for sounding the bells.

Similarletters refer to similar parts throughout the views.

The two bells aand b, independent of each other, are freely suspendedfrom a common screw-bolt m, supported by a suitable frame or base-platet'. The clappers or hammers c and at (one for each bell) are carried bybent levers c and d, fulcrumed side by side at o and 01 respectively, ina slotted bracket e, extending from a standard 70 of the base plate Theclapper levers are so arrangedthat their weighted ball-shaped ends orheads 0 and cl, respectively, will tend to keep the opposite or outerends, which project through the slotted bracket 6, together, Fig. 1.

Pivoted to the standard 7 at f is a doublearmed lever f, one arm ofwhich is formed with a wedge-shaped beak f adapted to be thrown or movedby a blow or shock between the said outer or free ends of the bentlevers in orderto part the latter and to operate thereby the clappers.For imparting to the beak f such a blow or shock a plunger g, sliding ina socket g, is arranged above the other or free end f of the leverf. Bya blow upon the head h of the plunger 9 the latter slides down andoscillates the double-armed lever f. The wedge-shaped end or beak f ofthe latter will thereby be forced, between the adjacent arms of the bentlevers c and al and the clappers c and d thus be caused to strike andsound both bells a and 1) simultaneously, in the construction shown thelarge bell a, for instance, being struck on the outer side by theclapper cl, While the small bell b is struck on the inner side by theother clapper c, as will be clearly understood from Fig. 2. The blow,and thereby the sounding of the bells, may be repeated as the plunger isagain raised by the back swinging or back oscillation of the lever f,which is effected by the action of the weighted clapper-levers upon thewedgeshaped beak f In some cases it maybe advantageous to effeet a morepositive return of the clapper-1evers into their position of rest, whichmay be accomplished by means of suitable springs. Instead of employing adouble-armed lever f, 'as above described, I may so arrange the bellsand clapper-levers that the plunger may be caused to act directly uponthe said clapperlevers. For this purpose the said plunger may beprovided with a wedge-shaped end or beak and with a suitable spring forreturning the same to its inoperative position. As these modificationsare selfevident, they need no further description and illustration.

Having fully described my invention, What I claim, and desire to secureby Letters Patent, is-

A signal or call bell comprising two concentrically-arranged bells,bell-crank hammer or clapper levers c d, the actuating-lever f and thepushaod it, said parts arranged for operation substantially asdescribed.
